The microblogging site initially added a warning still to the beginning of videos in question that users would have to bypass to see the clip. As first noted by The Verge, Twitter released a new version today that requires users to confirm that they are at least 17 years of age; the previous version described itself as suitable for users 12 and older.

However, the pop-up confirmation screen on version 1.0.5 appears to do little more to prevent access to questionable content than previous moves; children under the age of 17 lacking direct adult supervision can easily subvert this new obstacle to install the app.

CNET has contacted Twitter for comment on the new move and will update this report when we learn more.

The update follows similar moves by Tumblr and 500px, the latter of which was briefly removed from the Apple App Store presumably because of its photo-sharing capabilities, which might allow users to search for and find naked bodies.
